Background: Dapsone is a second-line therapy for immune thrombocytopenia (ITP). It cost-effective, with response rate comparable to other drugs used as therapy, such azathioprine, danazol, cyclophosphamide, cyclosporine, vincristine, rituximab, and eltrombopag.
 Material Methods: This retrospective study analyzed ten adult patients who presented our hematology division outpatient clinic be...

A 36-year-old woman presented with erythematous confluent macules on her whole body with fever and chills associated with jaundice after 8 months of dapsone therapy. Her symptoms had developed progressively, and a physical examination revealed bilateral cervical lymphadenopathy and splenomegaly. Excisional biopsy of a cervical lymph node showed effacement of the normal architecture with atypica...

The human species is becoming increasingly obese. Dapsone, which is extensively used across the globe for dermatological disorders, arachnid bites, and for treatment of several bacterial, fungal, and parasitic diseases, could be affected by obesity. We performed a clinical experiment, using optimal design, in volunteers weighing 44-150 kg, to identify the effect of obesity on dapsone pharmacoki...

The title compound, C(7)H(4)N(2)O(6)·C(12)H(12)N(2)O(2)S, is a 1:1 cocrystal of the drug dapsone with 3,5-dinitro-benzoic acid. The dihedral angle between the two aromatic rings of the dapsone mol-ecule is 75.4 (2)°, and the dihedral angles between these rings and that of the 3,5-dinitro-benzoic acid are 64.5 (2) and 68.4 (2)°. A strong inter-molecular carb-oxy-lic acid O-H⋯N(amine) hydrogen bo...

Sulfa drugs are widely used in the prophylaxis and treatment of Pneumocystis carinii pneumonia. Co-trimoxasole, the first-line agent, is a combination of sulfamethoxazole plus trimethoprim but functions as sulfa monotherapy since trimethoprim appears to be inactive. Dapsone, a sulfone, is a commonly used second line agent. Both sulfamethoxazole and dapsone act by binding to the dihydropteroate ...

In the title p-toluene-sulfonate salt of the drug dapsone, C12H13N2O2S(+)·C7H7O3S(-), the dihedral angle between the two aromatic rings of the dapsone monocation is 70.19 (17)° and those between these rings and that of the p-toluene-sulfonate anion are 72.34 (17) and 46.43 (17)°. All amine and aminium H atoms are involved in inter-molecular N-H⋯O hydrogen-bonding associations with sulfonyl O-at...

Although the preventive action of dapsone against P. falciparum malaria was known for many years, there was no report about the incidence of P. falciparum malaria in leprosy patients treated with dapsone, especially from areas of Southeast Asia where both leprosy and malaria are endemic. Therefore, two clinic-based malaria surveys were undertaken at a gap of 12 years, comprising 506 lepromatous...

The prevalence o f secondary resistance o f Mycobacterium leprae to dapsone (among leprom atous leprosy patients treated fo r a m inim um o f 5 years) has been estimated, from sur­ veys conducted before 1976 , to be 2 .5 /1 0 0 patients at risk in Malaysia, 3 /1 0 0 in Israel, 7 /1 0 0 in Costa Rica, and at least 1 0 /1 0 0 in Ethiopia. Apparent prim ary resistance to dapsone (among patients no...

Subcorneal pustular dermatosis is a disease that has coalescent, flaccid, recurrent pustules. We do not know everything about its etiology or pathogenesis; however, its autoimmune mechanism links it with neoplastic or immunologic diseases. First line treatment is dapsone. We describe the case of a classic subcorneal pustular dermatosis in a patient in who we could not use dapsone (sulpha drugs ...

Pemphigus vulgaris is an autoimmune disease characterized by suprabasal blisters with acantholysis, which has a fatal course in a large number of untreated patients. Systemic corticosteroid therapy is considered first-line therapy. Adjuvant treatment with the goal of sparing corticosteroids include, among others, dapsone. This drug is not without side effects and its use requires clinical and l...
